I had not been to Baguio City for quite some time until June of 2016 (last year). And so I took a lot of photos of the roads between Metro Manila and Baguio including the three expressways (NLEX, SCTEX and TPLEX) and Marcos Highway. I have only posted photos of Marcos Highway ( a lot of them) and haven’t come to downloading photos of TPLEX that I have taken during my first time along the entire stretch at the time. To sort of make up for the backlog, I am posting the following photos of Kennon Road that I took almost 7 months ago. I assume most if not all roadworks along Kennon Road that some of the following photos show are already completed. I will no longer write captions for each of the photos but there are many landmarks shown here that can help the reader in his/her sense of direction and orientation. The following photos are of Kennon Road from Rosario, La Union to Baguio.
More photos from that June 2016 trip soon…
My colleagues and I have been talking about accomplishments and legacies. In particular, we had a spirited discussion about what we have been doing in terms of transportation projects that we have been involved in. I think everyone wants to have something physical to remember them by. And these should be positive and constructive and not memories of controversies or anomalies like those in major projects that will be associated with corruption or abnormalities in the processes by which the projects were implemented.
The ‘problem’ with being involved in policy making and planning is that these often lead to outputs such as reports and maybe even laws. If one is lucky enough then perhaps its in the form of a legislation rather than a Department Order. But those legislations and memos often do not acknowledge the people who contributed to its drafting. They will be associated with the politicians (e.g., senators and congressmen) and officials (e.g., secretaries, undersecretaries) who sponsored, co-sponsored or issued them. It will be good to have some sort of evidence to show and prove that you were instrumental in planning, designing and/or implementing a project.
The appointment of a new Department of Transportation (DoTr) Secretary in Art Tugade had me recalling our meeting with him to present the outcomes of our study on a major commercial development at Clark Freeport. He was appreciative of our work and mentioned that Clark had implemented many of the recommendations of the Master Plan we had developed for the Freeport back in 2010. All the major recommendations were implemented during Tugade’s watch at Clark. Following are the most notable ones:
The Mabalacat Gate and Public Transport Terminal of the Clark Free Port Zone
McArthur Highway – M.A. Roxas Highway – First Street rotunda
The lead for these projects was Dr. Ricardo Sigua who is the one of the leading transportation engineers in the Philippines and currently the Director of the Institute of Civil Engineering of the University of the Philippines Diliman. He is also the head of the Road Safety Research Laboratory of the National Center for Transportation Studies where he is also a Research and Extension Fellow. Others involved in these projects were Dr. Karl Vergel, Dr. Noriel Christopher Tiglao and Dr. Jose Regin Regidor, all from UP Diliman and affiliated with the NCTS.
Still on Marcos Highway, the following photos complete this feature from my most recent trip to a city dubbed as the summer capital of the Philippines. This is the third part of the series on this major road to/from Baguio City, and sections pretty much show very similar characteristics as the previous ones in the preceding posts. Its been a while since the Part 2 of this series and since then, an additional section of the Tarlac-Pangasinan-La Union Expressway (TPLEX) has been opened further cutting down travel time between Manila and Baguio to 4 hours.
The approach to this curve reveals the uneven terrain on which the road was built.
These row houses and their driveways seem too close to the road
That’s a poorly placed driveway right in the middle of the curve
Many motorists tend to overtake slower moving vehicles via the opposing traffic lane. Here is a bus undertaking a passing maneuver at a curve!
Rockslide – these are frequent along mountain roads such as Marcos Highway. They are even more frequent along Kennon Road and Naguilian Highway.
Yet another section this time showing a reverse curve.
Here are a few more of the big bikes we encountered on our trip down from Baguio. These are of the same group of bikers in Parts 1 and 2.
Many sections of Marcos Highway have excellent sight distance and have usable, paved shoulders.
There is significant truck traffic along Marcos Highway. These, especially the loaded ones, often slow down traffic. In certain cases, trucks form platoons making it difficult to pass them.
I was not surprised to see a school along the highway since there are many communities along the road. This is a good example of standard signs and markings including a pedestrian crossing.
The curve is not a good location for a home.
The pavement at this section is intriguing as the road seems to have had a different orientation in the past. I suspect this was formerly a paved bay (for emergency stops or for loading/unloading passengers) in what used to be an unpaved shoulder.
The section shows also what looks like a bay along the inner (left in the photo) side of the highway. Note that the shoulder is rather narrow along the ridge-side (right).
Curve sections like this offer picturesque views but are actually are treacherous. The barriers are supposed to prevent vehicles from ‘flying’ out of the highway. Their designs should arrest large, heavy vehicles that may lose control and collide with the barriers.
Marcos Highway offers many breathtaking views and excellent sight distance along many portions.
This is the final stretch of Marcos Highway that terminates at the intersection with the Manila North Road, which is part of AH-26.
To open September, I continue on the feature on Marcos Highway. Following are more photos I took on our way back to Manila from a short vacation in Baguio.
Many sections of Marcos Highway have some form of protection against landslides or rock slides. Note the concrete faces fences along the left in the photo.
There are many structures along the highway including houses and stores
The mountain limits sight distance along curves like this.
We encountered this group of motorcyclists heading up to Baguio on what appeared to be what is termed as “big bikes”, that typically are the more expensive ones, too. Other photos in this series will show these motorcycles. I lost count of them while we were traveling the opposite direction.
This seems to be a popular stop for hungry travelers. The location though and its driveway are not at all desirable from the highway engineering perspective.
Combination of signs to guide motorists along this sharp curve.
Curved sections like this one offer breathtaking views of the mountains.
Shoulders may function as space for emergency stops including for breakdowns or changing tires. Full shoulders allow for stopped vehicles to be completely clear of the traveled way. That is, they don’t pose as obstacles that traffic would need to evade.
More examples of poorly located establishments along a curve
The road seems to disappear in the mountains
Conspicuous location for a religious site along the highway
More motorcyclists and their big bikes
Barriers along both side of the highway seem sturdy enough to keep vehicles from flying off the road in case their drivers/riders lose control. This section offers enough to satisfy sight distance requirements and noticeably does not feature double yellows like the other photos in this post.
A residential community along the highway including this big house just clear of the shoulder.
Another community including a home atop the mountain. The barriers appear to be newly constructed along with the PCC paved shoulders. These would have to be painted for them to be visible to motorists especially at night-time or when visibility is poor.
More photos of Marcos Highway soon!
In my recent trip to Baguio, I made sure to take new photos of roads particularly the major ones that made that city in the mountains accessible. Of course, one objective was also to have an updated selection for my highway engineering lectures. Following are the first batch of photos I took of Marcos Highway last June 2016. I won’t be writing a caption for many of these photos as well as those in the succeeding batches. I’ll just put these here for others to refer to whether for practical uses or for research.
I found it unusual to see double yellow along a relatively straight and level section of Marcos Highway. It is perhaps a section where there have been a significant number of road crashes?
There are rumble strips along many sections of the highway; seemingly there to wake up travelers that where getting sleepy.
It can get quite foggy along the highway
One end of the viaduct alongside the mountains
I thought perhaps bridges and viaducts in the Philippines should have shoulders and more generous space for pedestrians.
The van in the photo enters the highway from one of the many driveways and local roads connecting to the national highway.
What appears to be a tunnel for many people is actually a roof structure to protect travellers and the road from landslides.
During the day, it is bright inside the structure given the openings along one side of the highway.
The light at the end of the tunnel?
More photos in Part 2 coming up soon.
The 23rd Annual Conference of the Transportation Science Society of the Philippines (TSSP) was held at the University of the Philippines (UP) Diliman last August 8, 2016. It was hosted by the National Center for Transportation Studies (NCTS), which for some time was practically inactive in its dealings with the society. The conference was a very successful one with more than 170 participants, mostly students from the undergraduate programs of Mapua Institute of Technology (MIT), De La Salle University (DLSU) and UP Diliman.
The Proceedings of the 23rd Annual Conference contains 22 technical papers, which I have already listed in a previous post showing the technical program for the conference. The link is to the current website of the TSSP hosted by NCTS. Those wishing to have copies of the papers may download them directly from the link. Meanwhile, those interested in the presentations should contact the authors. Their contact information are stated in the paper and it is ethical to get the nod of the authors for their presentation file as these still fall under what can be defined as their intellectual property. I am aware of people who tend to get presentation slides and then pass them of as their work when they use the slides or the data/information therein. There are proper ways for citations of references and sources but sadly such ways are not observed by many.
